ImplementsComparable<DrmScheme>

A content protection scheme a StreamRequest can ask the platform player to honour. Not every platform plays every scheme; ask MediaManager.isDrmSupported(DrmScheme) first and pick the strongest scheme the device answers yes to.

A streaming service usually packages each title once with CENC and serves it with whichever scheme the requesting device supports: FairPlay to Apple devices, Widevine to Android, and HLS AES-128 where neither is available.

Enum constant details

AES_128

AES_128
HLS segment encryption with the key fetched from the URI of the playlist’s #EXT-X-KEY tag. Every native player that plays HLS decrypts it, so it works on the most devices. The key reaches the client in the clear (over TLS), which makes it a deterrent rather than hardware-backed protection: guard the key URL with a short-lived, per-session token.

CLEARKEY

CLEARKEY
The W3C ClearKey key system: CENC-encrypted media with keys delivered as a JSON Web Key set. The same packaging as Widevine without a license vendor, which makes it the scheme to develop and test a license server against.

WIDEVINE

WIDEVINE
Google Widevine, the protection Android devices implement, with hardware-backed keys (L1) on most phones.

FAIRPLAY

FAIRPLAY
Apple FairPlay Streaming, the protection iOS, iPadOS and tvOS implement. Needs the application certificate from Apple’s FairPlay program, set with DrmConfig.setCertificateUrl(String).
